This abstract class is a partial
implementation of the Set interface that makes it
easy to create custom Set implementations. Since
Set defines the same methods as
Collection, you can subclass
AbstractSet exactly as you would subclass
AbstractCollection. See
AbstractCollection for details. Note, however,
that when subclassing AbstractSet, you should be
sure that your add( ) method and your constructors
do not allow duplicate elements to be added to the set. See also
AbstractList.
